On the latest Billboard 200 albums chart (dated April 29), The Chainsmokers' Memories… Do No Open, bows at No. 1, granting the duo its first chart topper. The set starts with 221,000 equivalent album units earned in the week ending April 13, according to Nielsen Music. Elsewhere in the top 10, Pentatonix, Joey Bada$$ and Father John Misty all start in the region.

The Billboard 200 chart ranks the week's most popular albums based on their overall consumption. That overall unit figure combines pure album sales, track equivalent albums (TEA) and streaming equivalent albums (SEA).

Now, let's take a closer look at some of the action on the latest Billboard 200 chart:

- Soundtrack, Moana - No. 7 - The soundtrack to the hit film has now sold more than a half-million copies in the U.S., as it shifted another 24,000 copies in the week ending April 13, according to Nielsen Music. That brings its cumulative sales sum to 509,000. The set was released on Nov. 18, 2016 through Walt Disney Records.

Moana is the third soundtrack to surpass a half-million in sales in 2017, following Suicide Squad and Trolls. Suicide Squad passed the 500,000 mark in the week ending Jan. 26 (its sales now stand at 548,000), while Trolls crossed the half-million threshold in the week ending March 16 (its sales are currently at 573,000).

- Twenty One Pilots, Blurryface - No. 27 - Twenty One Pilots' former No. 1 Blurryface celebrates its 100th consecutive week on the tally. The set climbs 29-27 with 16,000 units (up less than 1 percent). In total, Blurryface has earned 2.9 million units, with 1.5 million in traditional album sales. The set launched four hits on the Alternative Songs chart (all of which reached the top two) and scored two top 10s on the Billboard Hot 100 with "Stressed Out" (No. 2) and "Ride" (No. 5).

Blurryface was the act's first No. 1 (and first top 10 effort), and launched atop the tally dated June 6, 2015. The album has never fallen out of the top 40 during its entire chart run, and has only gone as low as No. 36 (Dec. 12, 2015).

- Joey Feek, If Not For You - No. 50 - The late Joey Feek - of the husband and wife duo Joey + Rory - makes her solo Billboard chart debut, as her posthumous album If Not For You bows at No. 50 on the Billboard 200 and No. 6 on Top Country Albums. The archival set (its songs were recorded in 2005) earned 11,000 equivalent album units in the week ending April 13. Of that sum, 10,000 were in traditional album sales, according to Nielsen Music. Feek died March 4, 2016 of cancer.

- Deep Purple, Infinite - No. 105 - The band nets its highest-charting set in 26 years, as Infinite bows at No. 105 (7,000 units, nearly all from album sales). The act last went higher with the No. 87-peaking Slaves and Masters in 1990.

- Michelle Branch, Hopeless Romantic - No. 143 - Michelle Branch is back on the Billboard 200 after a long absence as Hopeless Romantic bows at No. 143. The set, her debut for Verve and first full-length solo album since 2003's Hotel Paper, launches with 5,000 equivalent album units earned in the week ending April 13, according to Nielsen Music. Nearly all of that sum was traditional album sales.

Branch last appeared on the tally as a soloist with Hotel Paper, which spent 33 weeks on the list in 2003 and 2004, debuting and peaking at No. 2. As half of country duo The Wreckers (alongside Jessica Harp), the pair hit No. 14 in 2006 with Stand Still, Look Pretty. Four years later, Branch released the country EP Everything Comes and Goes, which missed the Billboard 200 but reached No. 35 on Top Country Albums.

- ABBA, Gold - Greatest Hits - No. 200 - ABBA best-of Gold - Greatest Hits bounces back onto the chart (No. 200) for the first time in nearly three years (May 17, 2014; No. 176). The sturdy-selling collection has sold 5.7 million copies and is the 19th-biggest-selling greatest-hits album in the Nielsen Music era (which began in 1991). The top-selling hits package during that span is The Beatles' 1, with 12.8 million sold.
